STRAWESTACKER FoR THRESHING-MACHINES.

:EPECIFICATION forming part ofLetter. Patent N o. 7 24,098, dated March 31, 1903.

Application filed October 15, 1902. Serial No. 127,377. (No model.)

To all whom it may concern: v

Be it known that 1, JOHN HEINEKE, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Straw Stackers for Threshing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a straw-stacker in which l utilize a pneumatic or blower carrier or ejector in connection with an endless carrier, whereby the straw is taken from the separator by the blower and delivered to the endless carrier.

The object of the invention is to furnish a construction that will embody thewell-known merits of the blower to receive the straw from the separator and one that will provide for conveyance of the straw to the stack in a slow even stream without the objectionable blast delivery onto the stack from a pneumatic blower, to which is incident a constant cloud of dust andchaff that by itsrpresence renders the labor of the work men on the stack extremely difficult.

My present improvement has reference to a construction similar to that set forth in appli cation for Letters Patent of the United States filed March 15, 1902, Serial No. 98,391.

The invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a side elevation of my stacker.- Fig. II is a longitudinal section taken through;

the stacker. Fig. Ill is atop or plan viewof mechanism for hoisting the stacker chute.- Fig. IV is a view of a fragment of the hood or top of the stacker-chute.

1 designates a blower-tube that leads from a blower of any ordinary construction that is mounted in the separator or threshing' machine to which the stacker is applied. v

2 is a rotatable tube surroundin g the blower-I tube 1 and revolublymounted on a support 3, projecting from the rear end of the threshing-machine.

at is a chute that is mounted upon a pivot 5, seated in horizontal bars 6, that are fixed to the rotatable tube 2 and extending forwardly therefrom. The pivoto swingingly supports the chute 4, so that it may be moved vertically to any desired inclination for the delivery of straw therethrough to the stack.

7 designates lever-arms fixed to the side of the chute 4:, and 8 are Windlass-cords connected to the arms 7. The'cords 8 pass from the arms 7 to and beneath sheaves 9 and therefrom to drums 10, on which they are adapted to be wound for the purpose of raising and lowering the chute 4.. The sheaves 9 and drums 10 are mounted on shafts 11 and 12, which are seated in the horizontal bars 6.

13 is -a ratchet-wheel on the shaft 12, and

'14: is a pawl that engages with said ratchetwheel and prevents retrograde rotation of said shaft and the drums thereon.

15 is an endless carrier arranged on rollers 16 and 17, mounted in the chute 4 at its ends and adapted to travel through said chute. The shaft of the roller 16 has mounted upon it a pulley 18, that receives a belt 19, which is also applied to a pulley 20 on a driven shaft 21'. On the shaft 21 is also a pulley 22, that receives a driving-belt 23, through which power is communicated from the mechanism :of the "threshing-machine to the belt 19 to drive the endless carrier 15.

24: designates the hood or top of the chute 8o 4. This hood is formed with a closed forward end and beyond the closed portion is pro-' vided with a plurality of perforations 25 (see Figs. 11 and 1V) through which the air do li-vered into the chute 4 through the blowertube and rotatable tube'l is permitted to escape instead of acting as'a blast upon the strawafter it enters thechute and thereby tending to blow the straw through the chute.

,As a consequence of the exit of the air on whose duty it is to take the straw as it emerges from the chute and distribute it over the stack may stand close to the exit end of the chute without being discommoded in the least by the annoying feature of the blast and consequent dust incident to the forcible ejection of the straw that is present in all purely pneumatic or blast stackers. 1

I claim as my invention- 1. In a straw-stacker, the combination with a blower-tube receiving straw directly from a threshing-machine separator, of a chute having a bottom, side Walls and a top and having communication with said blower-tube, and an endless traveling carrier operatingin said chute to convey the straw through said chute on its delivery from said blower-tube, substantially as set forth.

2. In a straw-stacker, the combination with end and being provided with perforations at v its rear end, substantially as set forth.

JOHN I-IEINEKE.
